循环运算 meaning in Chinese
loop operation
Examples
- Obviously rc6 is not square - like cipher . square attack can only attack few rounds of rc6 , because the data - rotations of rc6 affact the rules of propagation for active and passive words , which makes square attack ineffective . we analyse the square attack against serpent which is bit - oriented cipher , and the result shows that square attack on serpent is weak , because the bit - oriented linear operations interrupt the rules of propagation for active and passive multiset
我们将square攻击应用于rc6密码,发现square攻击只能攻击少数几轮rc6 ,这主要是因为rc6的数据依赖循环运算打乱了活动字节和固定字节的传播路径,使得攻击无法进行。我们分析了对serpent密码的square攻击, serpent密码的按比特线性混合运算打乱了所构造multiset的传播路径,使得攻击只能进行到3轮serpent密码。 - The paper makes great efforts on the software optimization of evrc vocoder . based on the understanding of tms320c64xx cpu structure , we do deeply - optimization on the loop which appear usually in voice signal processing , and this improve the utility ratio of cpu and the parallelity degree of cpu function cell . at the same time , we utilize the bit - exact test to test the fixed - point evrc vocoder with the test vectors of tia / eia / is - 718 , which improve the robustness of the vocoder
本文围绕定点evrc声码器的软件优化，做了大量的工作，在充分理解tms320c64xxcpu结构的基础上，针对语音信号处理中大量出现的循环运算进行了深度优化，大大提高了cpu的利用率以及cpu功能单元的并行程度，同时，我们还用tia / eia / is - 718的测试向量对定点evrc声码器进行了严格比特对准测试，提高了声码器的鲁棒性。
